Alpha-Defensin vs Thymalin
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Alpha-Defensin
Alpha-defensins are small cationic peptides that are key components of the innate immune system. They have broad-spectrum antimicrobial activity against bacteria, fungi, and some viruses.
Full details →Thymalin
Thymalin is a polypeptide preparation derived from calf thymus. Developed in Russia, it has been used for decades to support immune function and has shown potential anti-aging effects in long-term studies.

| Aspect | Alpha-Defensin | Thymalin |
|---|---|---|
| Mechanism | Insert into microbial membranes to form pores, leading to cell death. Also have immunomodulatory effects including chemotaxis of immune cells and cytokine modulation. | Regulates the ratio of T-cell subpopulations, stimulates cellular immunity, and enhances phagocytosis. Also affects neuroendocrine regulation and may influence melatonin production. |
| Typical Dosage | Research compound - dosing varies by application. Typically studied in laboratory and early clinical research settings rather than for general use. | Clinical protocols: 5-20mg daily intramuscularly for 3-10 days. Often cycled 1-2 times per year for maintenance. |
| Administration | Various routes studied including topical, local injection, and systemic administration depending on application. | Intramuscular injection. Usually administered in short courses rather than continuously. Often combined with Epithalamin for anti-aging protocols. |
| Side Effects | Limited human use data. May cause local inflammation. Potential for immune activation effects. | Generally well-tolerated. May cause injection site reactions or temporary flu-like symptoms as immune function is modulated. |
